Holocaust denial

Holocaust denial refers to denial of an official policy by the Nazi government to exterminate Jews, which led to the killing of between 5-6 million Jews, a figure historically-accepted.

OHPI considers Holocaust denial as a form of antisemitism. It was recognised as such in the Working Definition of Antisemitism from the International Holocaust Remembrance Alliance (IHRA) which gives as an example of antisemitism: “denying the fact, scope, mechanisms (e.g. gas chambers) or intentionality of the genocide of the Jewish people at the hands of National Socialist Germany and its supporters and accomplices during World War II (the Holocaust)”. IHRA also has a Working Definition of Holocaust Denial and Distortion. We support both definitions and encourage their use, including by moderators of online content.

Below is a list of our publications documenting, reporting and highlighting instances of online racist speech.
